The Armadillo projection (also called the Raisz Armadillo projection or Orthoapsidal projection) is a world map projection that projects orthographically onto the surface of a torus with radii 1 and 1.
The projection was created by Erwin Raisz in 1943 and is distinguished by its three dimensional likeness to a curled armadillo.
